Figure 2. Microarray analysis of AmTRF expression under various conditions. Fold changes in the level of AmTRF message are shown for the following experiments: forager (F) head versus nurse (N) head, F brain v N brain, 8-day old brain v 7-day old brain, central brain (CB) v optic lobes (OL), F abdomen v N abdomen, mature queen (MQ) v virgin queen (VQ), early pupae head (ST1) v late pupae head (ST3), brains of light-exposed bees (L) v dark-kept (D) bees, brains of juvenile hormone treated bees (JH) v controls (CTRL), heads of caffeine and honey-fed bees (CAFF) v honey-fed bees (CTRL). Error bars represent standard deviations from 8 independent samples. Nurses refer to 1-day old bees, foragers to 20-30-days old bees.
